| complete mitochondrial genomes of living and extinct pigeons revise the timing of the columbiform radiation. | pigeons and doves (columbiformes) are one of the oldest and most diverse extant lineages of birds. however, the nature and timing of the group's evolutionary radiation remains poorly resolved, despite recent advances in dna sequencing and assembly and the growing database of pigeon mitochondrial genomes. one challenge has been to generate comparative data from the large number of extinct pigeon lineages, some of which are morphologically unique and therefore difficult to place in a phylogenetic ... | 2016 | 27782796 |
